As for the trunk open, do you pull up a lever on the floor next to your seat? If so that is a cable release and it won't work remotely.

I know there are similar forums for Hondas, might be better to post there as the folks on that board are more familiar with your car. I'm an engineer who understands vehicle electrical and happened to have owned a bunch of Hondas so I chimed in.

Good luck with the project and if you come across an accurate diagram for your car then send me a private message via the forum and I will be happy to take a look at it offline. I'm trying to keep this thread on track for Mercedes only.
